The Canopy Height Model(CHM) is the calculated difference between DSM and DTM, the first products of the LiDAR survey. The second entity is the canopy height model in 10 m resolution derived from the LiDAR survey. The helicopter-based survey of the Rio San Francisco catchment has been conducted in the periods of March 7-17, 2012 and November 12-19, 2012. Coordinate System UTM, Datum WGS84, Zone 17S, and Geoid EGM96 - for orthometric height - are used. The horizontal accuracy is within 5cm (based on control landmark of the IGM geodetic network). Quality assurance is done by visually inspection and correction of classification and ghost reflections. Additional quality control is done for completeness of the point cloud density and for models creation, which assured internal consistency of terrain representation (removal of artifacts due to misclassification) and seamless integration between tiles. Total data extent, considering all tiles is W: 704190.00, S: 9552910.00, N: 718190.00, E:9564110.00. The DTM has the spatial resolution of 1m, which is confirmed based on independent GPS control points measured on plane areas. The LiDAR survey has been carried out under the working group of Prof. J. Bendix. Operational support and quality check: Jörg Zeilinger, Brenner Silva, Thomaz Lotz

Additional Infos:

The usage of the LiDAR DSM/DTM is restricted to the RU816 members. The usage for publications has to be agreed in advance with Prof. J. Bendix. In addition please check the PAK 823-825 data user agreement. (www.tropicalmountainforest.org/dataagreementp3.do)
